This invention relates to a jogging mechanism for use in a tying machine, and its object is to provide a tying machine with an automatic jogger which will bring a series of bundles, or a series of box shocks into alignment without unduly compressing them, or injury thereto, and as soon as the jogger has struck the bundle it will stop at that point and not compress it more than is incidentally done due to the smart blow which 1t strikes the bundle with.

It will be understood by those familiar with the bundling machine art, that in bundling shocks, shingles and other thin objects of that character, that great care must be taken to align all of the units of the package, or else the packagewill be. very loosely tied, or the several unlts will be 1njured by having the wire cut into V-them and spoil them along the edges.

With the present invention the j ogger strikes the packages, aligns all of the several units as they may be loosely piled up in the tying machine, and as soon as the jogger has thereby aligned the units it stops and is held in that position throughout the time of the operation of the tie, thereby preventing the bundle from becoming disarranged during the tying operation, and as soon as the tying is completed the jogger is then restored to its outermost position by the operation of the parts automatically.

Another object of the jogger is to provide means for straightening up and aligning the several units of a package even though they are not very carefully aligned as the package is put into the machine, the jogger moving from eightto ten inches or a foot during each stroke, and then being automatically restored to its initial position at the end of the tying operation.

Other objects of the invention -Will be apparent as the description proceeds.

An embodiment of the invention is tshown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout the several figures of the drawings and of which there may be modifications.

' Figure 1 is a back elevation Io a complete tying machine having this jogging apparatus applied thereto, that is looking at the discharge side of the tying machine.

Y Figure 2 isa side elevation of the tying machine showing the relation of the j ogger to the fence against which the bundles of units are placed to be tied.

Figure 3 is a vertical sectional view through the jogging mechanism in a plane parallel to the main frame of the tying machine.

Figure 4 is la vertical sectional view through the gears which drive the jogger.

Only so much of .the tying machine as is necessary to illustrate the action of the jogger is shown, most of the operating parts of the tying machine being left oi for'purposes of clearness of illustration.

The numeral 1 represents thebase of the tying machine; 2 a lar e fixed ring which extends in a vertical p ane' from the base and which has supportingwheels 3 4, 5 and 6 to carry the shuttle ring '7.f rEhe base 1 is provided with a tablel 8, on one side of which there is a 'fixed `:fence or abutment 9 against which the 4bundlesy are Ipushed when they are to be tied. j

' The machine is driven by an electric motor 10 which is mounted upon a bracket or table j 11 at the top of the ring 2,fand has the belt 12 extending to a pulley 13 "on the shaft 14:

which carries a worm gear 15 inmesh with a worm wheel 16 on a shaft 17. ,The shaft 17 carries a cam 18 and a wheel 419 which is provided with a crank pin 20. The crank pin 20 is connected to ,a pitman 21 which. pitman has a series of rack teeth22 thereon at its upper end in mesh with a pinion gear 23. The pitman 21 slides through a box 24 which is plvotally mounted on the shaft 25.

The shaft 25 is mounted in two journal boxes 26, 27 and it has a bevel gear 28 thereon in mesh 30. The shaft 30 has a gear 31 thereon in mesh with a smaller gear `32 on a shaft 33 which shaft also has a larger gear 34 there- -on which gear drives the ring gear 7, and

also drives the gears operating the jogging mechanism. j

The gear 34' is in mesh with the gear 35 with a bevel gear 29 on the shaft on a shaft 36, which shaft is mounted in a suitable 'bearing 37. The 4'shaft 36 has a collar 38, and since it is used in longitudinal thrust as well, it'is held in a given position by having the hub of the gear 35 bear upon one end of the bearing 37, and a tubulal` member 39 and bolt 40 is used to bring the gear 35 snug up against the end of the `journal bearing, while at the same time the collar 38 is brought snug against the other end of the same bearing.

At the opposite end from the gear 35 the shaft 36 is provided with a long spline 41, and holds a threaded sleeve 42 on which a collar 43 is threaded, a nut 44 being used to (prevent the collar 43 from coming off the en of the thread. The threaded sleeve 42 is provided with two keys 45, 46, which engage key-ways in a bell shapd casting 47, said casting having a friction wearing disk secured thereto at 48. A heavy spiral spring 49 surrounds the bell shaped casting and bears u on the disk 43. In the space betweentge bell shaped casting and contacting with the end of the sleeve 42 and the flange 38 is a larger threaded sleeve 49', said sleeve beingslidable on the key 41. Y

' Suitably mounted on the threaded sleeve 49 is a collar 50, which collar carries a spur gear 51 rigidly connected thereto by means 0f a threaded collar 52. In the bracket 53 which supports the bearing 37 there is slidable a rod 54 which has gear teeth on its underside and which carries the jogger arm 55. The rack bar 54 which carries the jogger arm 55 is in engagement with a pinion 56 on a shaft 57 journalled in two bearings 58, 59 just below the bearing 37, and the shaft 57 also carries a gear 6() with a very wide series of teeth.l

A supporting rod 61 extends into a bracket 62 carried by the journal bearing 37 and supports a shell 63 which forms a guard for the gear 51, gear and driving member 47. The cam 18 operates on a small roller 63" on a bell crank 64 which is pivoted at 65 to the lower portion of the fixed ring 2, and it has a rod 165 pivotally connected to its other end and to a short arm 66 which is secured on the shaft 67 in a fixed position by means of a bolt 68.

In order to provide the proper cushioning effect the rack bar 54 has a heavy washer or c'ollar 80 thereon, which collar forms the backing for a leather pump washer 81 and thin metal washer 82 held in place on the endfof the bar 54. This -pump washer is held in place by a nut83 on the end of the rack bar, and this washer slides in a cylinder 84 which is threaded on the end of the bearing '85 in 'whichthe rack bar slides.

A plug 86- closes the end of the tube 84, a small valve 87 enables the air passing into said tube and out of it to be so controlled as to dampen the rapid movement of the rack bar 54.

The shaft 67 carries an eccentric 69 which bears upon a key which key in turn bears upon the rack bar 54, the object being to prevent the rebound of said shaft when it is pushed forwardly and the arm 55 jogs the pile of units into place.

The operation is as follows: Assuming a. loose pile of shooks to be placed upon the table 8 adjacent the fence 9 the machine will be started into operation to effect the tying. The first movement that takes place will cause the rotation of the shaft 36, and as the gear 51 is then in contact with the friction surface 48 with the spring 49 compressed the result will be to rotate the gear 56 and throw the jogger bar forward; about the same time the eccentric will be turned so that it engages the key 70 and presses upon the shaft 54, a spring 65 within the tube 265 permitting enough slack movement to prevent the eccentric from locking on the key 70. As soon as the jogger 6 strikes the bundle, the friction 48 will sli and the ear 51 will become disengaged rom the riction with the jogger bar held firmly in engagement with the bundle, but without any tendency to move in either direction.

As the tying ring returns to its initial position the gear 51 will reverse its direction ofv travel longitudinally of the shaft 36 and will come into engagement with the friction 48 so that at the end of the movement of the machine the -ogger bar will be restored to the position s own in Figure 1 ready for a subsequent operation.

Having thus described my invention, what I desire to secure by Letters Patent of the UnitedStates is as follows, but modifications may be made in car ing out the invention as shown in the ldsiawings and in the above particularly described form thereof, within the purview of the annexed claims:

1. A jogger mechanism for bundling machines comprising the combination with a bundling machine of a table to support the bundle, an abutment a inst which'the bundle is to be placed, a s idable jogger arm, a rack bar for the support of the arm, means to advance the rack bar to cause thejogger bar to strike the bundle a sharp blow, means to thereupon disenga e the jogger arm advancing mechanism t erefrom, and means to engage the jogger bar mechanism to retract said bar upon the completion of a tie.
